“Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. For he that is dead is freed from sin.” (Romans 6:4-7)
Secondly, spiritual baptism's overcoming nature is presented. In order to fully accomplish man's redemption, Christ had to die. He had to truly die so that He might be truly raised and be truly victorious. The immersion of the Spirit brings about an identification with Christ's death. Due to the power and presence of sin, death before life is a consistent theme in Scripture. The word that in verse four means in order that or so that. The reason for the death of the old inner man is so that, “...like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.” The preposition from carries with it the thought of out from the middle of. God the Father completely delivered the Son out from the very middle of death's grip, and so will He do for all that call upon Christ as Savior.
In Scripture, the old man is also referred to as the natural man and the carnal man. He is the flesh. In him dwells nothing good. He is in complete opposition to God and His ways; therefore, he must be dealt with if the believer is to be victorious. When the Spirit of God takes up residence in the repentant sinner, the old man is identified with Christ's crucifixion for sin and thereby rendered ineffective. The word destroyed means to nullify, invalidate, render useless or ineffective, or to abolish. It is the same verb rendered make...of none effect in Galatians 3:17. The regenerating work of the Holy Spirit invalidates the lordship of sin in the believer's life. Prior to salvation, a person is given to serve their lusts and their father, the devil (II Timothy 2:26, John 8:44). However, after the Spirit of God takes up residence, the believer is freed from such tyranny. The believer no longer has to be led about by lusts and passions. Sensual living can be a thing of the past. Victory is now possible! Immaturity and unfamiliarity with Scripture will keep a Christian from believing and practicing this amazing truth. The temper no longer has to control. The thought life no longer has to be vile. Actions no longer have to be dictated by circumstance. The Spirit's power is now present; and what power it is!
Verse seven is very strong in its language. The verb is freed is in the Greek perfect tense. Emphasis is being placed upon the fact of this freedom and its power at any given point in time. Regardless of circumstance, victory over the power of the flesh is always possible. The preposition from is emphasizing distance. God has placed a distance between the believer and his old ways and he is not to attempt a reunion.
